Function Documentation

lbm_print_init()

int lbm_print_init	(	lbm_uint *	print_stack_storage,
		lbm_uint	print_stack_size
	)

Initialize the print_value subsystem. print value depends on a stack and that stack is initialized here using a storage array provided by the user.

Parameters

print_stack_storage	Array to use as storage for stack data.
print_stack_size	The number of uint32_t elements in the array.

Returns

1 for success and 0 for failure.

lbm_print_value()

int lbm_print_value	(	char *	buf,
		unsigned int	len,
		lbm_value	t
	)

Print an lbm_value into a buffer provided by the user. If printing fails, the buffer may contain an error message.

Parameters

buf	Buffer to print into.
len	The size of the buffer in bytes.
t	The value to print.

Returns

negative number for failure and the number of printed characters on success.

lbm_value_is_printable_string()

bool lbm_value_is_printable_string	(	lbm_value	v,
		char **	str
	)

Check if an lbm_value (very likely) is a printable string

Parameters

v	Value to check stringyness of.

Returns

True if the value likely is a string, otherwise false.
